So I've had this spot on the back right side of my lower scalp upper neck for at least 3 years. I've been able to ignore it, but at times it'll get really itchy to the point where if I scratch it too much...clear liquid would come out. The skin is red in spots on my neck, but the skin on my scalp is said to be a different color than the rest of my skin. Almost like the skin is much thicker there. I don't think it's contagious bc many people have touched the area and don't get itchy...I don't know...can someone help me on what it is?
